PLEASE HELP - Does J2ME include java.lang.Math

I am trying to make a simple J2ME application that would do some
manipulation with trigonometric functions on floating point data, on a
handheld device. For prototyping purposes, I am using Sun
Microsystems' WTK 2.2, and the settings have CDLC 1.1. My source file
has the import:
import java.lang.Math;

I tried casting n as n11 = (double)n and then using this value, but it
has not helped.
Could some Java guru please suggest what a suitable solution might
be ? Any hints/suggestions would be greatly appreciated - thanks in
advance for your help.
